Municipal Council of Macau (Portuguese: Leal Senado, lit. Loyal Senate), was the local government structure in Macau (similar to city councils) during Portuguese colonial rule.

Macau or Macao (English: ; Portuguese: [mɐˈkaw]; Chinese: 澳門, Cantonese: [ōu.mǔːn]), officially the Macao Special Administrative Region of the People's Republic of China (MSAR), is a city and special administrative region of China in the western Pearl River Delta by the South China Sea. With a population of about 680,000 and an area of 32.9 km2 (12.7 sq mi), it is the most densely populated region in the world. Formerly a Portuguese colony, the territory of Portuguese Macau was first leased by the Ming dynasty to Portugal as a trading post in 1557. Portugal paid an annual rent and administered the territory under Chinese sovereignty until 1887. Portugal later gained perpetual colonial rights in the Sino-Portuguese Treaty of Peking. The colony remained under Portuguese rule until 1999, when it was transferred to China. Macau is a special administrative region of China, which maintains separate governing and economic systems from those of mainland China under the principle of "one country, two systems". The unique blend of Portuguese and Chinese architecture in the city's historic centre has resulted in its inscription on the UNESCO World Heritage List in 2005.Originally a sparsely populated collection of coastal islands, Macau, often referred to as the "Las Vegas of the East", since the late 20th century has become a major resort city and a top destination for gambling tourism. Its gambling industry is seven times larger than that of Las Vegas. The city has one of the highest per capita incomes in the world, US$43,770 in 2021, and its GDP per capita by purchasing power parity is one of the highest in the world.It has a very high Human Development Index, as calculated by the Macau government, and the fourth-highest life expectancy in the world.

Luis Ruiz Suárez S.J. (September 21, 1913 – July 26, 2011) was a Spanish-born Jesuit priest and missionary to China. Father Ruiz founded Casa Ricci Social Services, and later the Caritas Macau charity. His work in the 1950s focused mainly on refugees from mainland China. As Casa Ricci's works developed, it spawned Caritas Macau and Ruiz turned the focus of Casa Ricci to work with lepers and their families, and still later to those suffering from HIV/AIDS. He came to be known by several nicknames – "Luk Ngai" (in Cantonese), "Father of the Poor", and "Angel of Macau."

Caritas Macau is the charity outreach of the Diocese of Macau, Macau, China. It began in 1951 as an outgrowth of the charitable works of Luis Ruiz Suarez SJ, and his Casa Ricci Social Services.
